How to Read an Oscilloscope - GCSE and A Level Physics

This video explains how to read an oscilloscope. Oscilloscopes are often quite old and can be tricky to decipher. However it's not as bad as you think!
Oscilloscopes essentially displays a graph that changes in real time. The y-axis is potential difference (voltage) and the x-axis is time. An alternating current source will produce a sinusoidal wave signal on an oscilloscope whereas a direct current will produce a flat line.
For an alternating current source, the distance between two peaks is the time period of the wave, not the wavelength. The time base and the voltage scale of the oscilloscope can be altered in order to see the waveform more clearly.
Thanks for watching,

I am doing A levels and i just percieved that we must know how to read / use an oscilloscope for our practicals.Needless to say , i needed this.Thank you for teaching us sir.

[@Miles_Moraless]

THANK YOU SO MUCH! I NEED THIS.

[@PhysicsOnline]

Not a problem, they are tricky to set up, but once you have a play with the dials they seem a lot easier.

[@zoeevans946]

Thank you so much ! Was hoping to see this as I’m doing a waves topic and am interested in how these work

[@humzahquadri]

That was short and informative, a great investment of my time! Brilliantly explained

[@danielcorbett6511]

Without you my life wouldn't be worth living :)

[@bobjohnson5555]

agreed

[@AnimalUltrasoundAssociation]

Pretty extreme response to a physics video, but I like it.

[@badluck5873]

lol

[@chaaryagamage1511]

This is sooo helpful !! Thank you so much

[@ansha09]

thanks!! new sub

[@starulelaforeze4555]

THANK YOU

[@vladnickul]

The centimetres you are talking about are called DIVISIONS!

[@danielcorbett6511]

sorry big man

[@bobjohnson5555]

u thin you now bEtter than Louis pow arrogant!

[@fabihaareeba9657]

Seems a lot less confusing now😃

my brother: "So freaking annoying! Holy man"

[@mamathagopinath710]

I need to pass 8th grade exam

[@Unfortunatelebanese]

been a month since u commented, how was the exam :>

[@Eyebroooo]

​@@Michelle-ob2unhe failed yeah he told my mom

[@ingmarso9504]

I come here for physics lesson. What I talk does not represent my school opinion, lol. I think this video is in middle standard, not good, not bad lor.
